fedora
October 19, 2025
Update to 3.11.14
Summary
Python 3.11 is an accessible, high-level, dynamically typed, interpreted
programming language, designed with an emphasis on code readability.
It includes an extensive standard library, and has a vast ecosystem of
third-party libraries.
The python3.11 package provides the "python3.11" executable: the reference
interpreter for the Python language, version 3.
The majority of its standard library is provided in the python3.11-libs package,
which should be installed automatically along with python3.11.
The remaining parts of the Python standard library are broken out into the
python3.11-tkinter and python3.11-test packages, which may need to be installed
separately.
Documentation for Python is provided in the python3.11-docs package.
Packages containing additional libraries for Python are generally named with
the "python3.11-" prefix.
